02:45, 11/07/2024

On December 08, 2017, the Vietnam Ministry of Natural Resources and Environment issued Circular 57/2017/TT-BTNMT to provide specific guidance on determining the location for performing work during comprehensive marine resource survey.

According to Circular 08, the location for performing work during the comprehensive marine resource survey in Vietnam is defined as follows:

No.	Type of Work	Location	Notes
I. Station with wide surface
1	Marine meteorology	The highest point of the ship
2	Air environment	The highest point of the ship
3	Oceanography (measuring salinity, temperature, depth - CTD measurements)	Port (or starboard) stern of the ship
4	Sea water environment	Port (or starboard) stern of the ship	Conducted along with Oceanography (CTD measurements)
5	Marine geology	Port (or starboard) stern of the ship
6	Marine sediment environment	Port (or starboard) stern of the ship	Conducted along with Marine geology
7	Seafloor topography	Port (or starboard) stern of the ship	Depth is measured continuously along the journey and coordinates are determined at the station
8	Marine ecology	Port (or starboard) bow of the ship
II. Continuous station
1	Marine meteorology	The highest point of the ship
2	Air environment	The highest point of the ship
3	Oceanography (CTD measurements)	Port (or starboard) stern of the ship
4	Sea water environment	Port (or starboard) stern of the ship	Conducted along with Oceanography (CTD measurements)
5	Marine sediment environment	Port (or starboard) stern of the ship
6	Marine ecology	Port (or starboard) bow of the ship
III. Ship moving from one station to another
1	Seafloor topography	Port (or starboard) stern of the ship	Along the journey according to sections
2	Marine ecology	Port (or starboard) stern of the ship	Surveying and sampling, fish traps
3	Air environment	The highest point of the ship	Sampling dust along the journey
IV. Independent buoy station
1	Oceanography (measuring currents, sea level, and waves)	Buoy stations spaced apart and from the ship by 200 - 500 meters not including the length of the ship's mooring rope	Continuous measurement for 7 days and nights or as required

Details may be found in Circular 57/2017/TT-BTNMT effective from September 3, 2018.
